How do you say "Nice to meet you / Please treat me well" in Japanese?

Quick use

Use よろしく おねがいします (yoroshiku onegai shimasu) with friends or new people when you meet someone for the first time. It is meant to be short, polite, and easy to say under pressure.

Chunk or pattern

• Treat よろしく おねがいします as one useful chunk first.
• Do not worry about rebuilding it from grammar every time. The fastest win is to recognize it, say it, and hear the reply that usually comes after it.

Helper words and endings

• Learn the full line first. The small pieces are secondary unless you keep hearing them in other set phrases.
• ます: is a polite verb ending.
• おねがいします: softens the request into a polite "please". In many everyday lines, it is easier to learn the whole ending as a chunk.

Practical note

The polite request ending does a lot of work here. Even if the rest of your Japanese is simple, this keeps the line sounding cooperative.
